Car transmission disc gear

Transmission gears frequently operate under conditions of high speed, high load, and constantly changing speed and load. In addition to normal wear and tear, gear damage can also be caused by poor lubricant quality, poor lubrication conditions, improper driving operation, and improper gear meshing during maintenance. These factors can lead to gear impact, poor tooth meshing, and start-up vibration, all of which accelerate gear wear and damage. Gears rely on their structural dimensions and material strength to withstand external loads, requiring materials with high strength, toughness, and wear resistance. Due to the complex shape and high precision requirements of gears, the materials must also have good processability. Forged steel is commonly used for transmission gears.

New energy vehicle products

New energy vehicles (NEVs) refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels with new on-board power devices), integrating advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles and new technologies and structures. NEVs include four main types: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as supercapacitors, flywheels, and other high-efficiency energy storage devices). Unconventional automotive fuels refer to fuels other than gasoline and diesel.
